Comparision of 2 and 4 stroke






Comparision of 2 and 4 stroke
The two stroke engine gives an engine which..
1.has high power / mass ratio
2.is easy to reverse
3.has a reduced number of moving parts and consequently requires less maintenance

Where as the 4 stroke
1.good volumetric efficiency
2.good combustion characteristics
3.positive exhaust scavenging
4.less arduous lubrication requirements due to idle strokes which allow spread of lubricating oil through bearings and around the liner.
